▎ 摘　　要

NOVELTY - A combination of substrate chosen from silicon, silicon carbide or metal and graphene precursor is treated, to obtain polyphenylene intermediate. Polyphenylene intermediate is then converted into graphene. The graphene precursor has an aromatic structure which forms the basis of the graphene structure, and at least two different types of functional groups which can react with each other to grow the graphene structure by forming additional carbocyclic aromatic structure. The functional group is chosen from carbon-carbon double bonds, carbon-carbon triple bonds, dienes and ketones. USE - Production of graphene used in production of graphene-based nanostructures for electronic applications. ADVANTAGE - The method enables production of graphene by simple process. DETAILED DESCRIPTION - A combination of substrate chosen from silicon, silicon carbide or metal and graphene precursor is treated, to obtain polyphenylene intermediate. Polyphenylene intermediate is then converted into graphene. The graphene precursor has an aromatic structure which forms the basis of the graphene structure, and at least two different types of functional groups which can react with each other to grow the graphene structure by forming additional carbocyclic aromatic structure. The functional group is chosen from carbon-carbon double bonds, carbon-carbon triple bonds, dienes and ketones. The aromatic structure is benzene, naphthalene, pyrene, anthracene, chrysene, coronene and/or phenanthrene, or cyclic or acyclic structure which can be converted to aromatic structure.
